Hello Moult,
My name is Antonia Gates, I manage the games at CoolmathGames.com. I really enjoyed Caterwaul, I think it would be a great fit on our site!
I'm writing to ask if the game is available for non-exclusive licensing. Our licenses are totally non-exclusive, so you would maintain all of the IP rights and could continue to develop and distribute the game however you'd like to.
Please let me know if it is available, and how much it would cost. I'm looking forward to discussing this with you soon!
Best regards,
Antonia Gates
